So, I figured an earlier 'import cPickle as pickle' statement could be the problem. However, I've changed all such lines from my code, and still get the same error. A grep -r of the egg cache shows that a couple modules in ZODB3-3.10.5-py2.7 do use the 'import cPickle as pickle' statement ( only in ZEO/scripts/zeoqueue.py, ZODB/utils.py & ZODB/tests/testUtils.py), but it doesn't work if I change those either.

There is an 'import pickle' line immediately before the block where this error is raised. Why then, is it not importing the pure-python version of pickle? Any ideas??</div><div><br></div><div>Cheers,</div><div>Alex</div><div><br></div><div><br></div><div><br></div><div><div></div></div></div></div></body></html>
